Key Similarities
| Symptom | How it is similar |
|---|---|
| Perfectionism | Both eating disorders and OCD can involve intense standards, fear of mistakes, and difficulty feeling that things are acceptable or complete. |
| Compulsive or repetitive behaviours | Both can involve repeated behaviours that feel difficult to resist and are often used to reduce distress or regain a sense of control. |
| Strong need to be in control | Both can involve a persistent need for control, which may show up through routines, rules, checking, or rigid patterns of behaviour. |
| Intrusive unwanted thoughts | Both can involve unwanted thoughts that feel distressing and hard to dismiss, even when the person does not want to have them. |
| Feeling constantly anxious or on edge | Both can involve ongoing anxiety and tension, which can make daily life feel mentally and emotionally exhausting. |
